17 . Find the values of g(9) and h(-14) and add them together.
The function equations are given to find their values substitute 9 in g(x) and -14 in h(x)
20. They said f(x) = 2x + 9 and f(x) = 15 , which means they are equal to each other.
So write them as 2x + 9 = 15 , and solve the equation to find the value of x.
25. Here all you have to do is substitute 4 into the f(x) equation to find f(4)and you will have your answer.
Hope this helped!
There are two formulae you can use to calculate the number of apple trees and the number of conifer
trees for the pattern described on the previous page:
Number of apple trees = n2
Number of conifer trees = 8n
where n is the number of rows of apple trees
There is a value of n for which the number of apple trees equals the number of conifer trees.
Find the value of n and show your method of calculating this.

Answer:
n = 8
Step-by-step explanation:
"By inspection" is an appropriate method.
We are asked to compare the expressions
n·n
8·n
and find the value(s) of n that makes them equal. By inspection, we see that n=8 will make these expressions equal. We also know that both expressions will be zero when n=0.
__
More formally, we could write ...
n^2 = 8n . . . . the two formulas give the same value
n^2 -8n = 0 . . . . rearrange to standard form
n(n -8) = 0 . . . . . factor
Using the zero product rule, we know the solutions will be the values of n that make the factors zero. Those values are ...
n = 0 . . . . . makes the factor n = 0
n = 8 . . . . . makes the factor (n-8) = 0
Generally, we're not interested in "trivial" solutions (n=0), so the only value of n that is of interest is n = 8.

A lot of times, I find a graphing calculator to be a quick and easy way to find function argument values that make expressions equal.
1. Which inequality matches the graph ?*
Answer: x < -1.
Step-by-step explanation: That is the answer. Everything less than -1.
Answer:
x < -1
Step-by-step explanation:
Your answer is correct: it has an empty circle (which means it is either < or > not including). The arrow also points to the left, meaning less than or <
The scale on a map is 1cm : 4 km. if two cities are 14 cm apart on the map, what is the actual distance between the cities?
Answer:
The actual distance is 56
Step-by-step explanation:
set up a proportion
1cm 14cm
=
4km x
cross multiply 56=x
so the actual distance is 56 km im pretty sure :)
The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.
How much does an ounce of the chemical cost in 2005? (Do NOT type the $ with your answer.)
9514 1404 393
Answer:
$98.15
Step-by-step explanation:
2005 is 15 years after 1990. Using the formula we find ...
c(15) = 63·1.03^15 ≈ 63·1.55797
c(15) ≈ 98.152
An ounce of the chemical costs about $98.15 in 2005.
HELP PLEASE ILL GIVE 20PTS AND BRAINLIEST TO RIGHT ANSWER
Answer:
Step-by-step explanation:
x + 90° + 73° = 180° ( being linear pair)
x = 180° - 163 °
x = 17°
Answer:
Measure of angle AD = 90 Degrees since its a right angle
Also
Measure of angle BC = 90 degrees as it is also a right angle.
Now,
From AD:
90 - 73 = 17 degrees
As AD and BC are same concurrent angles. So,
x = 17 degrees
Hope it helps you. Do mark me as brainlist.

Step-by-step explanation:
F is directly proportional to a . If F = 28 when a = 7 find, a when F = 40
asap
Answer:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
3x times 4=7x-(x+17) please help me
Answer:
x = ⁻¹⁷⁄₆ or -2.83333333333Explanation:
3x · 4 = 7x - (x + 17)
Simplify both sides of the equation
3x (4) = 7x − (x + 17)
3x (4) = 7x + −1 (x + 17) (Distribute the Negative Sign)
3x (4) = 7x + −1x + (−1) (17)
3x (4) = 7x + −x + −17
12x = 7x + −x + −17
12x = (7x + −x) + (−17) (Combine Like Terms)
12x = 6x + −17
12x = 6x − 17
Subtract 6x from both sides
12x − 6x = 6x − 17 − 6x
6x = −17
Divide both sides by 6
6x / 6 = −17 / 6
Simplify
x = ⁻¹⁷⁄₆
Turn the fraction into a decimal
-17 ÷ 6 = -2.83333333333
x = ⁻¹⁷⁄₆ or -2.83333333333a is the point with coordinates (1,4) b is the point with coordinates (7,22) Find the gradient AB
Answer:
The gradient AB is 3
Step-by-step explanation:
Here. we want to find the gradient AB
This is the same as finding the slope of the line that connects the two points
mathematically. we have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (1,4)
(x2,y2) = (7,22)
m = (22-4)/(7-1) = 18/6 = 3

. Bryon competes on the school debate team. He won 0.40 of the debates in which he participated. Which statement is not true about Byron's debates?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Since Bryon won 0.40 of his debate, this means that he won 40% of his debate. 40% converted to fraction equals 40/100 = 2/5.
Since he won 40%, it means that he lost (100% - 40%) = 60%. He lost 3/5 and won 2/5.

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?
Answer:
1/15
Step-by-step explanation:
Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?
The amount of cereal she would have per day is calculated as:
5 days = 1/3 of the box
1 day = x
Cross Multiply
5 days × x = 1 day × 1/3 of the box
x = 1/3 ÷ 5
x = 1/3 × 1/5
x = 1/15 of the box

At a sale this week, a desk is being sold for $133 . This is 35% of the original price.
What is the original price?
Answer:
392.35
Step-by-step explanation:
35% + 35% is 70 % so 133 +133 is 70 % witch is 269.
next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this
3000 ÷ 133 = 22.56 is 30% of 133
70% + 30% = 100%
269 + 22.56= 291.56 is your answer

2/5 = X/70
Answer:
28=x
Step-by-step explanation:
2/5=x/70
(70/1)(2/5)=x/70(70/1)
here you cancel 70 into 5 to get 14 and on the other side cancel both the 70s
14*2=x
28=x
Answer:
28
Step-by-step explanation:
multiply 2 * 70 then divide by 5

The speeds (in miles per hour) of motorists ticketed during one day on a five-mile stretch of highway are
listed below.
80, 70, 89, 85, 85, 75, 72, 73, 80, 83, 86, 88, 88, 70, 89, 74, 75, 84, 73, 71
The mean speed is 79.5 mph with a standard deviation of 6.8 m.
If the police decide to only ticket people going 3 standard deviations or more above the standard deviation, what would the range be?
Your answer:
Answer:
19
Step-by-step explanation:
Range is solved by subtracting the lowest and highest numbers which int his case is 70 and 89 so that make 19
